Title: Remote measurement of electrical active power
Inventor: LEE ROBERT SUTTON
IPC: G01R21/06
Filed: 2017-11-16
Abstract: A system for remotely measuring the active power flowing through an electrical conductor 1 from an alternating current (AC) source 16 to a load 15 comprises a first unit A located on or near the conductor and a second unit Belectrically connected to the AC source. The first unit comprises a cur­rent transformer 3 mounted in close proximity to the conductor, a storage means 7 for storing energy from the current transformer, a processor 8, and a wireless transmitter 6. A switch 9 is controlled by the processor to selectively switch a resistor 10 in parallel with the current transformer to sample the voltage across the resistor. The processor then performs a Fast Fourier Transform on the voltage samples and transmits to the second unit a signal representing the variables output by the transform. The second unit comprises a receiver 13 to receive the signal from the first unit and is configured to measure the voltage of the AC power source. From this, and the received variables, the real power and direction of electricity flowing in the conductor is calculated.

Title: Spatial audio capture
Inventor: JUHA TAPIO VILKAMO
IPC: H04S7/00
Filed: 2018-03-27
Abstract: Spatial audio signal processing comprising receiving audio signals from a microphone array comprising at least three microphones forming a geometry with defined displacements between pairs of the three or more microphones. This is followed by determining delay information between audio signals associated with pairs of the at least three microphones, determine an operator based on the geometry with defined displacements between the pairs and applying the operator to the delay information to generate at least one direction parameter. Preferably a pair of microphones of the three or more are identified, before a normalised coherence value associated with the audio signal of the pair is determined. This is then output as an energy ratio parameter. Preferably the pair of microphones identified, are the pair with the largest displacement. Preferably, displacement vectors associated with the displacement between the pairs of three or more microphones are formulated. These vectors are then used to formulate a displacement matrix. Displacement vectors which are associated with pairs of microphones with unreliable delay information are removed from the matrix.

Title: Drinking water heater with venting fitting
Inventor: WILLI HECKING
IPC: F24H1/18
Filed: 2018-12-03
Abstract: The venting fitting (10, figure 1) is installed in a feed pipe (12, figure 1) of a drinking water heater with an air cushion. The fitting has a housing with a housing interior 102 located between a water inlet 36 and outlet 38. The fitting also has at least one air inlet 42 connected to atmosphere and having an air pressure chamber (134, figure 15) defined between an air inlet valve (e.g. backflow preventer 116) and a moveable lifting element (e.g. piston 108). Movement of the element causes a volume and pressure change in the chamber, with the air inlet valve permitting air to enter the chamber from ambient when the chamber pressure falls sufficiently. A one-way air outlet valve (e.g. grooved ring 130, figure 15) permits air to pass from the chamber into the housing interior and mix with water when the air chamber reaches a pre-set pressure. A drive moves the element. The drive may comprise a turbine wheel 74 that turns when there is water flow through the fitting to move the element back and forth via a gear system. Alternatively, an electric motor may drive the element when water flow through the fitting is sensed.

Title: Optimised network deployment
Inventor: TIMOTHY GLOVER
IPC: H04L12/24
Filed: 2019-03-25
Abstract: A method to configure a network for a specific deployment environment. A plan 420 is created which represents environmental features including an indication of locations where network element deployment is precluded. A network specification 422, a forecast demand for the network 410 and the plan 420 are provided as inputs to a network optimiser 404. An initial version of network layout 424 is created and fed into the network optimiser along with a measure of a performance metric 408. The network optimiser iteratively searches a library 406 which contains possible adaptations that can be applied to the network layout to satisfy the forecast demand and which will also improve the performance metric. The network optimiser uses heuristic search techniques, such as simulated annealing, hill climbing or guided local search, to search the library. The iterative search may be terminated when the improved performance metric meets a threshold value. The search results in a sequence of adaptations being identified that when implemented modify the network layout 424 such that on deployment a measure of the performance metric satisfies the threshold value. The plan may be a digital map of a geographic area that includes identification of premises.

Title: Control system and method for controlling a vehicle
Inventor: GEMMA WHARTON
IPC: B62D6/00
Filed: 2019-03-26
Abstract: A control system 110 for an autonomous vehicle receives a signal indicating a rate of change of a steering angle of the vehicle and also a requested steering angle, for example from an autonomous vehicle controller 130. A ratio is determined based on the current rate of change and a steering angle rate of change limit. The requested steering angle is adapted based on the ratio, for example by multiplying the requested steering angle by the ratio, by applying a correction or by using a proportional-integral-derivative algorithm, and may then be used to control a steering mechanism 120. The ratio may be modified by applying a gain and a saturation function may be applied. A vehicle, method, computer readable medium and a system including the control system and a steering mechanism are also claimed.

Title: Block propagation with poisoned transactions in a blockchain network
Inventor: STEVEN PATRICK COUGHLAN
IPC: H04L9/32
Filed: 2020-04-21
Abstract: In traditional proof of work (POW) blockchains successful blocks must be propagated to other miners for checking to achieve consensus. As blocks get bigger transmission delays increase leading to more ‘double winners’ and forking. Previously, (e.g. GB2582978) flooding blocks from all miners before the POW succeeds to reduce post success latencies is suggested. Here, it is recognised that other miners can copy validated transactions from these speculative blocks. Thereby avoiding validation work/effort and acting unfairly. The invention poisons the transmitted early blocks by hiding deliberate errors/invalid transactions in them, so that transactions cannot be reliably copied without revalidation. This destroys the value of the early blocks to other miners. As claimed encrypted corrections are included with the poisoned block and the decryption key is transmitted by the successful miner to facilitate checking by other miners. In embodiments, other miners validate early blocks to find errors and compare these to corrections when/if a decryption key is received.

Title: A crystalline film of carbon nanotubes
Inventor: ABRAM FALK
IPC: B01J20/20
Filed: 2019-01-28
Abstract: A membrane is electrically charged to a polarity. A surface of carbon nanotubes (CNTs) in a solution is caused to acquire a charge of the polarity. The solution is filtered through the membrane. An electromagnetic repulsion between the membrane of the polarity and the CNTs of the polarity causes the CNTs to spontaneously align to form a crystalline structure.
